Using Database Technologies in Building Learning Community to Improve Knowledge Exchange

We utilize web and database technology to construct a Journal-Based Portfolios Assessment system to realize a Legitimate Peripheral Participation (LPP)[1] learning community. In this system, we divide system to three layer, the view layer present data by Oracle Portal Server, Data layer store data by Oracle Database Server and Operating Control layer operate workflow by Oracle Database trigger and job Data analysis and questionnaire indicates that Web Journal is effective to promote knowledge exchange, Student can improve learning performance and it can form a LPP structure The purpose of using the journal approach[2] is to emulate the forming of academic societies formed by journals. At the same time, the achievement of students in a course is based on their publications in journals and the positions they played in the journals. First, students submit their work such as homeworks, learning portfolios, reports of organizing contents in the discussion, learning problems, related websites. Each submitted article would be assessed by three peers Then the reviewers will review the submitted works. The reviewers will give comments to students. The journal system will publish good articles. Articles published include submitted works and reviewer’s comments hoping that students will contribute and exchange their knowledge.
